We can't yet build wearable devices that accurately monitor internal health markers without invasive testing.

open Global / Unspecified, Global

Current wearables track surface-level signals like heart rate well, but measuring things like blood chemistry non-invasively remains far less reliable. Solving this could make preventive healthcare monitoring dramatically more accessible.

We can't yet guarantee that autonomous vehicles will make the same safe decisions a careful human driver would in every situation.

open Global / Unspecified, Global

Self-driving systems handle most driving scenarios well, but rare, unusual situations still trip them up in ways human drivers might handle intuitively. Closing this reliability gap remains essential before full autonomy becomes truly safe.

We can't yet make voice assistants understand context and nuance as well as a human listener would.

We can't yet build affordable, reusable spacecraft capable of routine trips beyond low Earth orbit.

open United States, North America

Almost all current reusable rocket technology is built for missions close to Earth, while deep space missions still rely on expensive, largely disposable hardware. Extending reusability further out could reshape space exploration economics.

We haven't built a practical way to clean up the growing amount of debris orbiting Earth.
